Be Contented with whatever state you are in. You DON'T need this or that to be happy. Happiness is knowing Who You Truly Are and Just Be IT!
So......how to know who we trully are??
ask yourself... ask your conscience... and even if there's something you don't quite like about yourself, ...
you know you can change to become better person. If you dedicate every moment to self improvement, you will be happy.
